Astronomers pinpoint mysterious radio signals to a binary star system in the Big Dipper.
Scientists have traced mysterious radio signals, detected repeatedly over years, to a binary star system in the Big Dipper constellation.
The signals, lasting seconds to minutes, originate from a red dwarf and white dwarf star whose orbiting magnetic fields create these pulses.
This discovery differs from the usual neutron star sources and sheds new light on the origins of such radio phenomena.
